Purchased 1st CO2 Setup

This is a discussion on Purchased 1st CO2 Setup within the Freshwater Aquarium Equipment forums, part of the Beginner Freshwater Aquarium category; -->
I know there are cheaper ways to go about a CO2 setup, but i felt like spoiling myself with money from selling my calculus ...

as long as it works thats what matters. Just a suggestion. I ran my system on only one tank for a few years. Then I put on a 3 way splitter that I got for a few dollars. Currently mine runs two tanks but can run 3 max.Posted via Mobile Device

Well I will eventually want to have multiple tanks so thanks for the idea :DPosted via Mobile Device

Started it today at 1 bubble every 3 seconds, wanted to see how efficient the EXT5000 reactor really is and already my pH has dropped from about 7.5-7.6 to 7.1-7.2, I'm using the Milwaukee pH 600 handheld meter. So far so good!

I did a kH test and it was at 7. But i've read that the kH vs pH graph to guesstimate the CO2 ppm concentration is only helpful if you have a carbonate buffer.. so I don't think this will help me considering I do not.

BUT, my discus haven't seemed to get affectedf, it is a closed top tank (for my cat to stay out of it! lol), so I run aeration 24/7. While my CO2 system is wired to the T5 HO light timer for the 10 hour photoperiod.

Yes, even with adequate surface agitation under the glass cover, the fish where gasping for air (before co2 system was added). So I have been using an air stone 24/7 to fix the gasping. Also, the 84-86 degree water holds less dissolved oxygen.

Closed top combined with high temps = low oxygen

Its a 75 g with only 5- 4 inch discus, 3 cherry barbs, and a small group of corys.
